CyberMotion Simulator

The MPI CyberMotion Simulator was developed at the Max Planck Institute for Biological Cybernetics as a novel alternative to traditional motion simulators. It is based on a commercial six-axes serial robot originally designed for use in industries as manipulator. The use of this robot as a motion simulator offers many advantages over standard Stewart platforms with a hexapod motion system, for example higher dexterity, larger motion envelopes, sustained centrifugal accelerations, and the possibility to place subjects in extreme orientations (e.g. upside-down).

The CyberMotion Simulator (CMS) offers a unique facility that can accommodate many different perception, cognition and action experiments. The experimental studies that are conducted on the CMS include fundamental studies on human self-motion perception, motion cueing, spatial orientation, pilot modeling, tele-operation and EEG studies.

The CMS consists of an industrial robot arm with six independent axes, extended with an L-shaped cabin axis. The seventh axis allows for varying the orientation of the cabin with respect to the robot arm by changing the location of the cabin's attachment point from behind the seat to under the seat, or any intermediate position. Recently, the CMS has been further extended with a linear axis of ten meters. The resulting eight degrees-of-freedom (DOF) provide an exceptionally large workspace. Several extreme motions and positions can be achieved, such as large lateral/longitudinal motions, sustained centrifugal motions, infinite head-centered rotation, and up-side-down motions. Such motions and positions cannot be achieved in conventional simulator architectures, which makes the CMS a unique test bed for studies into motion perception and spatial orientation. To ensure the synchronous motion of the robot axes and the external axes (cabin and linear axis) custom software was developed. This software combines/distributes the signals coming from/going to the respective axes while making sure all timing requirements are met. Furthermore it also monitors the safety status of the system ensuring very high safety standards.

The cabin (including the cabin axis) was custom built, and allows for mounting a range of different input/control devices:
  • Button boxes (custom built) 
  • Pointing devices (custom built) 
  • Car steering wheel and pedals (Sensodrive GmbH) 
  • Helicopter collective (Wittenstein aerospace & simulation GmbH) 
  • Helicopter cyclic (Wittenstein aerospace & simulation GmbH) 
  • Side-stick (Wittenstein aerospace & simulation GmbH) 

The cabin is equipped with a stereo projection system (eyevis GmbH) with a field-of-view (FOV) of 140ºH x 70ºV and a resolution of 1920 x 1200 on each projector. High fidelity 3D visualization can be achieved with projection filters and glasses (Infitec).
